Аннотация
A stoichiometric lithium niobate crystal (LiNbO3 st) and congruent lithium niobate crystals grown from a charge prepared using cyclohexanone as an extractant (LiNbO3 cong(CHN)) and a charge prepared using cyclohexanone and carboxylic acid dimethylamides as extractants (LiNbO3 cong(CHN + A)) have been characterized by photoinduced light scattering and laser conoscopy. The results demonstrate that the LiNbO3 cong(CHN + A) crystals are rather homogeneous along their growth direction and possess good optical properties, similar to those of the LiNbO3 cong(CHN) crystal. At the same time, the LiNbO3 cong(CHN + A) crystal offers significantly better electro-optical properties (re = 29.3 pm/V).
